BUCKLE.

To all whom it may concern: Be it known that we, CHARLES S. HU r- INGTONand ARTHUR S. HUNrINeroN,.c1t1- 'zens of the United States, residing atOmaha,

in the county of Douglas and State of Ne- I braska, have jointlyinvented certain new and useful Improvements in Buckles, of which thefollowing is a specification.

It is the object of our invention to produce a strong buckle frame fromwire or other metal rod ata minimum cost ofmanufacture and withoutheating the same. 7 To accomplish this result, after the wire has beenbent to form the buckle frame or loop, the ends I t of the wire or rodare overlappedand then cold swage'd together and crimped, bent, or

dented to. prevent the two ends of the wire from pulling apart and alsoto provide a seat for the tongue of the buckle.

In the accompanyingdrawings we have illustrated two embodiments of'ourinvention wherein Figure 1 is a view of one form of incom-.

plete buckle frame showing the ends of the wire interfitted but notcrimped; Fig. 2 is a v1'ew similar to Fig. lfa-nd illustrates the mannerof bending or crimping the overlapped orinterfitted ends of the wire toprevent them from pulling apart and to form a seat for the tongue of thebuckle; Fig. 3 illustrates a modified method of manufacturing thebuckle, wherein the two ends of the wire forming the buckle frame aremerely overlapped but not interfitted, as shown in Fig. 1

Fig. 4 shows the buckle frame of Fig. 3 after it has been cold swaged topress the two ends of the wire together into firm contact and to crimpthem; and Fig. 5 is a view of the com pletedbuckle.

. Referringfirst to Figs. 1 and 2 it will be apparent that a strip'ofwire of the pro er length is'trimmed or out so that one em is providedwith a V-shaped notch or-so'cket 1 1, while the other end has asimilarly shaped tongue 12 adapted to fit in the socket. The

length of wire is then bent into the shape shown in Fig. 1 with its twoends'interfitted,

as shown, the tongue 12 fitting in socket 11.

In order to interlock these two terminal por- J tions of the wiretogether'in such a manner Specification of Letters Patent.

i that they cannot be readily pulled apart the interfitted ends are coldswaged' so as to bring them into firm contact and bend or :crimp them at13' thereby positively locking them together and forming a seat ordepression for the-buckle tongue. The joint of the buckle frame whenmade in thisrmanner is almost imperceptible and if the buckle is metalcoated afterwards the joint is so nicely covered that it is found onlywith difficulty.

In'Figs. 3, 4 and 6 we have illustrated a modified form of buckle frame,and in this type of buckle the ends 14 and '15 of the wire, which isbent to form the frame, are

made tapering and then overlapped when the wire is bent to shape toformthe frame, as shown in Fig. 8. In order to bring these twoends into firmengagement and to-prevent their separation they are cold swage'dtogether and crimped at 16, as shown in Fig.

4. This *crimping, as in the previous instance, positively locks the twoends of the wire together and forms a seat for the tongue 17, shown inFig.5. v

It will be obvious to those skilled in the art that changes may be madein the method of manufacturing. this buckle and in its constructionwithout departing from the essen-.

tial 1principles of the invention which are set fort in the followingclaims.

I claim:

1. In a buckle, thecombination of a frame made of a strip of wire or thelike,-the ends of which are interfitted and crimped or bent to interlockthem together and form a seat for a
